Hi,
One good thing about these MT4 indicators is that they come with source code in MQ4 file format. This means you can break it down and manually analyze what it is supposed to do, and make adjustments when necessary. Likewise, the Forex scalping indicators have been tested by experienced professional Forex traders. The indicators are not rehashed and they employ proven mathematical algorithms in the program. Additional alerts are also available and can easily be installed if required.
